Summary
NSW aquatic ecosystems data visualised on an interactive map.
Description
Export Data NSW Department of Climate Change, Energy, Environment and Water (DCCEEW Water) has adopted the Guidelines for Identifying High Ecological Value Aquatic Ecosystems (HEVAE) framework developed by the Australian Commonwealth Government. In the current assessment for NSW, the HEVAE consists of four key criteria which include diversity, distinctiveness, naturalness and vital habitat. Therefore, the HEVAE instream value layer is a combination of four individual criterion layers. The final or overall HEVAE score is determined for each River Style® reach. This is calculated by adding together the final scores for each criterion (Naturalness, Diversity, Distinctiveness and Vital Habitat). This score is then standardised by dividing by the maximum combined HEVAE score for a whole catchment's river reaches to provide an even spread of score outcomes between 0 (lowest) and 1 (highest). The distinctiveness value criteria of HEVAE were updated in 2018 by including the predicted threatened fish species distribution data (MaxEnt modelled data) provided by DPI Fisheries. The final or overall HEVAE scores where then recalculated after this process. Previous SEED service moved from 10.7 to 11. 1 Portal. Waiting for Metadata from DPIE.
